Course Title: Corrosion

12 Professional Development Hours/1.2 CEUs

Course Description: The Corrosion course explains the corrosion of metals, beginning with the electromotive series and the relation of activity potential to susceptibility for corrosion. The different forms of corrosion are given, along with illustrations detailing each. A guide to corrosion control is provided, which includes an explanation of the corrosion resistant metals, recommendations for surface treatments and a checklist for corrosion protection. A section on design for corrosion resistance in automotive bodies is also included which contains information on chemical reactions, likely locations of corrosion on the vehicle body, and typical resistance treatments used in the automotive industry. Design recommendations for minimizing corrosion potential and commonly used tests for evaluating corrosion resistance, are also detailed in the course.
